Thanks for the interesting article on the ice age timings of colder and warmer. <The unstable nature of the Earth's climate history suggests that it may be liable to change suddenly in the future. By putting large quantities of greenhouse gases into the atmosphere, humans are exerting pressure on the climate system which might produce a drastic change without much prior warning. As the geologist W.S. Broecker has said, "Climate is an angry beast, and we are poking it with sticks". > True enough, except that they give it a negative slant. It is more likely, given that the more common state of Earth is lots of ice, that we are stopping the sudden change to glacial, rather than creating a sudden change to warmer, which is what we are now in. I think of us as beating the angry beast back with our sticks, rather than poking it with our sticks. The periodicity of warm spells seems to be similar to eruptions for the Taupo caldera, though I haven't checked the timing. Taupo erupts when the magma chamber is refilled and the pressure down is not enough to control the pressure up and the whole column of liquids turns to gas in a stupendously colossal "geyser" of frothy pumice and exploding flammable gases. It's BIG! There are other periodic events large enough to change the climate, especially if they hit a harmonic in their periods. Mqurice
